MACHINE FOR FILLING AND CLOSING PAPER BAGS.

and Improved Machine for Filling and Closing Paper Bags, of which the following is a specification.

This invention relates to a machine of novel construction for filling and closing paper bags, small sacks, paper boxes and similar articles. The machine comprises a rotary carrier that presents the bag in succession to the various filling and closing means. These means shake the filled bag to effect a leveling and uniform distribution of the charge, insert a card or similar article therein, adjust the bag to a predetermined height, and then fold down successively the front, back and side flaps. In this way the bag is evenly filled and tightly closed in a quick and reliable manner.

Upon a power shaft 2 is mounted a worm 3 having a steep pitch for about one third of its length. The worm operates a rotary carrier 1 adapted to present the bag to the successive shaking, leveling, closing and other devices, and provided with a number of work holders 5, and a corresponding number of rollers'G, These rollers are adapted Specification of Letters Patent.

Application filed November 27, 1909.

Serial No. 530,110.

to consecutively engage worm 3, by the pitch of which the carrier is advanced a distance sufficient to carry a holder 5 from one of the,

operating devices to the succeeding device.

Each holder is composed of an upright box open at one side, and of a supporting plate 7. The latter is by rod 8 guided in an arm 9 of head 1, and is influenced by a spring 10 which engages rod 8, and tends to raise plate 7. Rod 8 is provided with teeth I 11 (Fig. 9) engaged by a pawl 12. During part of the rotation of carrier 1, pawl 12 is held out of engagement with rack 11, by a lgil 15,)that engages an arm 12 of the pawl The bags to be filled are received by two of the holders at a and b, and conveyed by the carrier to a suitable manual or automatic filling device located at a. During this operation andsubsequently thereto, the bags are held in their upright position by rails 13 engaging notches 4t, and located in front of the bags. I

The bags are shaken at d, at which point there is located beneath the holder, a rod 16 having an upper nose or projection 20. Rod 16 is raised by a spring 17, and carries a projection or roller 18, arranged within the path of a disk 19 having a plurality of projections and mounted on shaft 2. Rod 16 passes with its projection 20 over a projection 21 of rod 8 pertaining to that holder 5 which has been moved toward 0. When carrier 1 is arrested, disk 19 will by its projections and the roller 18 draw down rod 16 at short intervals against action of spring 17 Rod 16 will in turn draw down rod 8, which is likewise raised by its spring after each depression. In this way plate 7 receives a shaking movement, which is imparted to the bag supported thereon, so that the contents of the latter are uniformly distributed over the entire width of the bag.

After the shaking operation, the bag is by the carrier advanced to point e, where a card, folded directions for use, or similar device is introduced into the bag. The cards are contained in an obliquely arranged open magazine 23 (Fig. 7) having a lower egress slit 2 1. In front of this slit is provided an adjustable plate 25, that may be set according to the thickness of the cards, and permits but a single cardto pass at atime outof the magazine. The card ejecting means comprise a rotary arm 26 mounted-atright angles to a shaft 27 which is by bevel gear,

1 vided with laterallyarranged rollers 35.

During the rotation of the arm, the beak of the pin will enter a slit of the magazine bottom to grasp and withdraw the lowermost card. Rollers 35 will during this operation engage 'the magazine bottom, so that its beak will move in parallelism therewith. The hook transmits the card to a hopper from which it falls into the bag held open by a spreader. As shown the spreader is composed of four arms 37 which are pivoted to a cross piece 38,'vertically adjustable on shaft 39. This shaft has a roller 40 engaging eccentric disk 41 of shaft 31 (Fig. 1), so that shaft 39 will descend by gravity when .the narrow side of the disk is presented to the roller. The spreader arms are provided with tappets 45, that engage stops 44 so that the holders are turned or spread in a hori-- zontal direction shortly preceding the end of the stroke. After the card has been introduced into the bag, shaft 39 together with arms 37 is again raised by disk 41.

In order to tightly close the charged bag,

whether the same be filled to a greater or p less extent, it is subjected to the plunger mechanism located at the point Here the bag is so set that the surface of its contents is placed at a specific elevation. Above the bag is located 'a plunger 46 connected to a rod 47. To this rod is pivoted a lever 48, having a roller that engages a disk fast 011 shaft 31, whereby the plunger is reciprocated. The plunger enters the bag and bears upon the charge contained therein, so that it will forcethe bag against the action of spring-influenced bottom plate 7, down to a predetermined elevation. During the subsequent ascent of the plunger, the bottom plate is by pawl 12 held against ascent so that it will remain at the level to which it has been set by the plunger.

At 9 is located the mechanism for folding the bag into the form shown in Fig. 13, and to cover its back flap with an adhesive. The

folding. means comprise a slide.51, provided with a pair of rotatable jaws 52, and a pair of fixed jaws 54. The forward end of slide 51 engages by a roller, an eccentric disk 53 of shaft 29. Jaws 54 are provided w th a bearing 55, in which is journaled a spindle 56. This spindle has lower tappets 57 engaging corresponding grooves of aws 52, and an upper crank arm 58. To the latter is fulcrumed a rod 60 carrying stop 59 and .frame. Slide 51 is advanced by eccentric 53 during which movement jaws 52 will fold down that portion of the bag which extends forwardly above its charge, while at the same time jaws 54 will be moved sidewise along such protruding 'bag end. During this advance of the slide, rod 60 will by stop 59 strike post 61, whereby spindle 56 is turned, to spread jaws 52 by tappets 57. The jaws will thus spread the side flaps and press the same against jaws 54, so that the superposed layers are laid tightly against each other more especially at the folds.

Above the bag is mounted a brush or similar device 64 pivoted to rod 65, which is in turn by a cross arm rigidly connected to rod 66. The latter is at its lower end pivoted to a lever 67 which is actuated by an eccentric of shaft 31. The brush carrying arm is provided with a pair of tappets 69, 70, of which tappet 69 is adapted to be'depressed by a spring 71. To tappet70 is pivoted a pawl 72 which is spring-pressed into a notch of rod 65. The brushnormally occupies the position shown in dotted lines Fig. 11. If slide 51 is advanced, brush 64 is raised by lever 67 to engage an adhesive transmitting roller 73. This roller is coated with the adhesive by a roller 75, operated by belt 74, and dipping into a paste pot. During the further upward movement of the brush, an

.so that it clears roller 73 during its descent.

Directly prior to the end of its downstroke, during which jaws 52, 54 will again recede, brush 64 will by arm 69 strike an abutment 78, whereby it is swung into the position shown in full lines Fig. 11. In this position the brush is pressed against the rear protruding portion of the bag, which is supported by a suitable brace, so that during this movement and during the subsequent short ascent of the brush, the inner face of the bag flap is covered with the adhesive.

At 72, the rear flap of the bag is folded as indicated in Fig. 16. In the plane of the top of the bag-charge is arranged a horizontally slidable folder 80. The folder has a wedge shaped forward end provided with an inclined bottom, and is attached by a rod 81, and arm 82 to a slotted lever 83. This lever encompasses shaft 29 and engages with a roller, a cam 84 of said shaft. Upon rotation of cam 84, folder 80 is moved to the right, so as tofirst engage the center of the back bag flaps near its top, and gradually press such flap downward and toward both sides.

Above the bag there are hung on a rod 85, a pair of jaws 86 having tappets 89. This rod is by a cross piece connected to a rod 87 to which is pivoted a lever 88 operated by an eccentric of shaft 31. When folder 80 is advanced, jaws 86 are moved downwardly and outwardly over the side flaps of the bag, so asto hold them in position during the folding operation. When the jaws have approximately reached their lowermost position, tappets 89 will engage adjustable stops 90, whereby the jaws are so turned, that they will be tightly pressed against the side flaps, and press such flaps against folder 80, so that the superposed paper sheets will be forced tightly against each other.

At 2' the two side flaps of the bags are to be projected over the folded front and rear flaps, .while the side flaps are received by slits 92. Above the bag is located a cross arm 96 to which are pivoted a pair of claws 97 that are linked to a vertically movable rod 98. This rod is in turn linked to a lever 99 that carries a roller and is influenced by a spring 100. The roller engages a cam surface 101 of disk 84, by which lever 99 is so turned when plate 91 is projected over the bag, that claws 97 are swung into the position indicated by dotted lines Fig. 19, and fold the lateral bag-flaps upon plate 91.

After the claws and the folding plate have receded, the bag is moved to position k where it is ejected from the holder and delivered to a chute or similar device. The ejecting of the bag is efiected by means of a horizontally movable stripper 103 guided by a rod 102. This rod has a roller 10 1 engaging cam of shaft 29. By this cam, rod 102 is advanced at the proper moment, to move stripper 103 against the bag, and push the same out of holder 5, after which the stripper recedes, and a further movement of the carriers takes place.
